Overview State listed as significantly rare and proposed for upgrade to species of special concern Only just beginning to collect coast-wide population and distribution data (first coast-wide survey conducted in 2004) Biologists with NC State University, Cape Lookout NS and Cape Hatteras NS have been monitoring oystercatchers on barrier island beaches since late 1990s Additional data needed on oystercatchers nesting at non- traditional sites

3
Breeding Population and Distribution 2004 was the first year NC conducted a coast-wide survey for breeding oystercatchers 701 individuals (337 pairs) counted Many found on remaining undeveloped barrier islands (e.g. Masonboro, Core Banks, Hatteras) About half the population found on barrier island beaches and half on estuarine islands

Upcoming 2007 Coast-wide Survey Surveys for oystercatchers conducted in conjunction with colonial waterbird and piping plover surveys State Wildlife Grant funding will be used to conduct another complete survey this coming breeding season Need to cover approximately 311 linear miles of coastline plus estuaries Conducted with help from partnering agencies

Productivity Monitoring on Estuarine Islands Only one study looking at success on estuarine islands in NC (McGowan et al. 2005) Important to look at non-traditional sites -- 50% of NC’s oystercatchers nesting on estuarine islands Two projects recently afforded us the opportunity to try to collect additional data on natural and man-made islands in the sounds –Bogue Inlet channel relocation project –Parnell Island social attraction study near Oregon Inlet

Summary of Bogue Inlet Nesting Birds did poorly in both 2005 and 2006 -- nests likely being lost to overwash, predation and human disturbance Interesting to note that in 2006 many of the lost chicks were fairly old (out of 4 pairs that hatched and lost broods, three had chicks that were into their 2 nd and 3 rd weeks when they disappeared) Plan on monitoring nests near Bogue Inlet at least through 2008

18
Condition of Habitats Birds using dredged material islands and marsh islands with fringing beach Most dredge islands state- owned and posted Islands far from mainland so few mammalian predators Evidence of mink and possibly rats on some islands Human disturbance and gulls can also be a problem In general, little forage on dredged material islands

22
Summary of Oregon Inlet Nesting In general, birds on Oregon Inlet islands appear to be doing fairly well when compared with birds in other areas Dredge island nesters may be impacted by proximity of food to nest sites Need to try to increase protection of state-owned sites (better signage, increased enforcement, someone stationed in northern part of state in future) Continue to work with the Corps to direct timing and placement of material and create new islands in area

25
Other Actions Across the State Working with Fort Fisher State Recreation Area to get extra protection –Predator control –Better human control Better protection at Masonboro Island Continue to be involved in review of beach stabilization projects and require environmental commitments to benefit oystercatcher and other waterbirds Completion of beach-nesting bird brochure
